I have a list of names (surnames) and a simple search mechanism. I would like to have words with minor changes (typos) shown in search results.
Example search text: braniecka
Example result: Branicka, Kraniecka, Braniecki
Any help appreciated.

You can implement the Levenshtein distance. It is a widely used algorithm.
You could also consider upgrading your solution to Lucene, especially if you are doing any production work. Lucene handles your requirement in an extremely performant way (no brute-force exhaustive search).

Try using simmetrics.
Is a library for measuring string similarity and implements many algorithms.

I have a list that I made with a type I created of . I want to sort it in lexicographical order. I have seen the compareTo in Java, am I supposed to use this? I'm not sure how to put it into the lexographical format from a list? Can anyone show me an example? I have seen many examples, but I am not sure how to do it from a list.
Just use implement the Comparable<Type> in your own Type class and implement the compareTo method to match the lexicographical order. Than just call Collections.sort(yourlistOfTypes).

I'm trying to implement an stack using a linked list in Java, But I'm not sure which methods I have to implement(stack is a simple example here), How can I somehow get the methods and then extend my linked list class to implement my own class of stack
I know that somehow I have to use some kind of interface but it would be a great help if someone could guide me here.
A stack at its simplest just has Push() and Pop(). They map directly to the LinkedList methods push and pop already present!
So in order to implement a stack on top of a linked list you need to do....nothing :)

I have just come across a string variable in my application code where the value is assigned as follows
String YEAR="${year}";
What does the value of the String variable here?
Without being interpolated, just ${year}.
I can almost guarantee that String is going to be interpolated elsewhere in the code.
Maven, for example, uses this syntax to inject variable values into it's configuration settings.
Use an IDE such as IntelliJ and do a find usage on this variable. An extended find (search/find in path) may also yield results.
As others here have suggested, It is most likely being interpolated somewhere else.

I have below string which I get from an xml file.
<product>
<aa>1367</aa>
<ac>133787</ac>
<db>13345</db>
<ce>133</ce>
<er>135</er>
<et>130</et>
<ef>14</ef>
</product>
How do I convert it to an two dimension array like
product[][]={{"aa", "1367"},{"ac","133787"}, {"db","13345"}....}
I only want to use string function and loop.
I think the best way is to use an available XML parser.
In this thread: Best XML parser for Java you'll probably find which one is the best to use

In the class java.lang.Math there are several trigonometric methods like sin, sinh, asin, similarly for cosine. I read the descriptions but couldnot able to understand their differences. So please help me on understanding their differences.
Please explain in simple way as I have already read the documentation and could not understand. So I need more simpler language ffrom the documentation.
I think that you need some mathematical background, to understand the functions you have listed. The wikipeida is a good start. I really doubt that someone will explain you the trigonometry in a single answer in a way that you will understand.
http://en.wikipedia.org/wiki/Trigonometric_functions - this is for the sine, cosine, arcossine and etc.
http://en.wikipedia.org/wiki/Hyperbolic_geometry - this is for sinh, cosh and etc.
